HOT-WATER PIPE OR FITTING FOR COOKING-=STOVES.

SPECIFICATION forming part of Letters Patent No. 358,123, dated February 22,1887.

Application filed December 30, 1885. Serial No 187,092. (No model.)

To all whom it may concern:

Be it known that we, JOHN OKEEFE and CHARLES H. FILLEY, of the city of St. Louis, State of Missouri, have made certain new and useful Improvements in Hot-Water Pipes or Fittings for Cooking-Stoves, of which the following is a full, clear, and exact description.

In the accompanying drawings, Figure 1 represents a perspective side view of the interior of a cooking-stove fitted with our invention; and Figs. 2 and 3, detached side elevation and plan, respectively, to an enlarged scale, of the center shown in Fig. 1, with the various parts of our invention combined therewith.

Like letters of reference indicate like parts in all the figures.

A represents a box or casting, which is secured in a longitudinal position to the under side of the long center B of the cooking-stove by lugs a a and screws and bolts b b, (as hereinafter more particularly referred to,) and chambered or cored out along its interior, as shown by dotted lines at a, so as to form the main portion of the exit or hot-water pipe D, which is continued therefrom and passes through the side of the stove. The cold-water pipe E, on entering the stove, dips down for a short distance into the fire-box F, across which it extends horizontally, and thence upward to the box or casting A, with the interior 0 of which it communicates, so that a perfect circulation of water is established, through the combined pipes D and E, with the interior of the box or casting A. By this arrangement the cold-water pipe E is the only pipe that is in the fire-box F, and, being of small diameter, will heat quickly without interfering with the operations of the stove or collecting the ashes. The hot-water pipe D, being principally formed within the box or casting A, which is directly over the fire, receives additional heat as the products of combustion are passing from the fire-box F to the flues surrounding the oven, and does not chill the latter, as is the case when the hot-water pipe D passes along the top of the oven. The box or casting A also protects the under side of the long center B from the direct action of the fire, so that the center itself cannot be overheated or warped as in the existing arrangements.

The lug a, for securing one end of the box or casting A to the long center B, is slotted, as shown by the dotted lines in Fig. 3, so that in coupling the external portions of the pipes D and E to the main and service pipes outside the stove the box or casting A, with its bolt 1), can give to the adjustment required. The lug a, at the other end of the box or casting A, rests on theledge of the stove which supports the long center B, so that when the bolt 1), which secures thebox or casting A thereat to the center B, is loosened from the box or casting A, thecenter B can be lifted off the stove without disturbing the box or casting A, with its combined hot and cold water pipes D and E, so that these can be easily got at, or, if desired, removed altogether from the stove, and the long center B replaced.

We are aware that water-boxes secured to the central panel of a stove for the purpose of increasing the strength of the same, as is described in Letters Patent No. 258,098, and dated May 16, 1882, are not new, and we do not desire to claim the same, broadly. Nor do we desire to claim the system of combined fireback and water-pipes shown and described in Letters Patent No. 277,009, dated May 8, 1883.

We claim as our invention- In combination with a cooking-stove having a long panel, B, a water-box, A, slotted lugs a, and a screw or bolt, 2), lug a and screw or bolt 12', and supply and exitrpipes E D, substantially as and for the purpose specified.

In testimony whereof we have affixed our signatures, in presence of two witnesses, this 26th day of December, 1885.
